HERBERT W. CBANIL OF CHICAGO, ILLINOIS,

EXHAUST-GAS CONVEYER.

. Be it known Athat I. HERBERT W. CRANE, acitizen of the United States,residing at Chicagzqxigfin the, county-'of Cook and State ofIllinoisihave invented `certainnew and useful Improvements Ain-ExhaustLGas Convey` ers, of whichthe following is a specification. Myinvention relates 'to Ventilating or waste. gas conveyingdevices and hasparticular reference. to a novel exhaust gas conduit for automobilegarages or the like.

It is well known that in garages the engines of the automobiles storedtherein are frequently allowed* to operate fordiferent "purposes withthe result-that the space rap idly becomes filledy with. the exhaustedand g Myrinvention has'f tsprincipal object the provision" of'mea'nsWherebyf an automobile "f er reachingitsstall orlocation within thegarage has its exhaust pipe atl once connected to the'v exhaust gasconduit and may thereafter operatea'sflong asdesired. Thisprovisionpermitsz-the engine to be started when preparingfto leave thegarage,' and provisionA is also r nade for permittingthe automobile toproceed without referenceV to the connection With.the. waste l-gasconduit, the .parts being disconnected automatically; -Theinven't'ionf.willl be morereadily understood'byreference to theaccompany-ing tlrawingsgwherein- I Y Figure Lisv a plangvi W ,of l aportion iof the chassis ofgiiril'automobile., theeiihaust pipeof .whichis connectedl to one unit of my; novel V'Waste gas conveyer; `2 is alongitudinal sect-ion through one of the units referred to; `Fig: 3. isa section vthrough the main exhaust, conduit showing in detail theone-way valve controlling. each inlet; 4 isa f ragment'ary lan viewfofthe attaeh ing end ofI the flexible conductor; Fig. 5 .is anenlargedfragmentary section through` m novel flexible metallic tube incontracted position; and Fig. 6 is a similaryiew showing the helices'distended. K

Referring more particularly to the draw# ings itfwill'- be seen thatIprovide a. com r-` atively large, longitudinally extending s eet metalconduit. 10 having at. intervals therein inlets or elbowsl 11, the innerends 12 of which, as indicated in Figs. land 3, are curved in thedirection indicated by the arrow in Fig. 1, in order that the openingtherethrough may present in a line corre- Specication of Letters Patent.

sponding to the direction of travel of the l gases. The mouth of thiscurved portion is closed b a flap valve 13 hinged at 14 and normallymaintained in closed position by gravity. Thus it will be seen that ifbut one engine is connected to thev pipe the exhaust gases therefromcannot escape through any of the unused inlets 11, the valve 13maintaining such inlet closed. The extreme end of the conduit 10islikewise provided with a fla) valve 15, as indicated in Figs. 2 and 3,t is valve being adapted to swing inwardly. This arrangement is made inorder that the passage. of gases through the conduit may not be retardedby reason of a reductionvo pressure in a dead portion-of the conduit. Incase of a reductionof pressure at a point behind one of the outlets thevalve 15 will permit the entrance of atmospheric air.

Secured to the protruding end of the inlet or elbow 11 is a short tube16 secured to which is a metallic flexible hose 17. This flexible memberis constructedra's best shown in Figs. 5 and 6by'interlocking'aplurality.

of flanged helices, each member of which is in the form of a double,reversed -channel the extreme flanged `edgesof whiehoverliel andunderlie the corresponding ilangesofv Iadjacent members; .Thenecessity'for a metall'ic. hose of this lcharacter arises from the fact that theexhaust gases from the en- Awhich'the collar 19 is secured'to theexhaust pipe, extends transversely throughthe pipe Patented Oct. 6,1914.

andcollar and acts as a fastening device in Aconnection with the hookedrocker 21 pivoted Aat 22.5 A chain 23 is .connected to the rocker and toa 4bracketQa secured to the pipe v16 and tends 4to rotate the rocker 21whenever theportion-18 is Inoved longitudinally with respect to theconduit 10. vThus when the parts are connectedif ,the car' should bestarted the flexible tube 17 'would' be distended, the chain rocking thepart 21 and disconnecting the same .from the attaching pin. It will beunderstood that the collar 19 remains on the end of the car exhaustpipe. A spring 25 connected to the shaft 22 tends to maintain the rocker21 in the position shown in Fig. 2.

' lt will bc understood that in operation one of the conduits is placedalong the wall on each sideof the garage. A plurality of theinlets 11 isprovided, these inlets being' located at a convenient distance apart inorder to register with cars which are backed iii-to place. Each of theinlets 1l is provided witbli flexible hose and connector and as soon asafcni is backed into place the attendant connects the-iree-end of thehose to the cavxhaiist pipe. The parts re main in this position vnii-tilAthe lc ar is again started. It will beuiiderstood that an engine isusually operated for a shorttime prior to the departure of the car andinas much as the connecting parts would be very hot it would beinconvenient, if not impossible, to disconnect the saine manually. By myarrangement the operator is enabled to depart with the car withoutfurther atten-A tion to the connection with the exhaust outlet.

It is obvious that the'construction shown is only typical of other formswhich the invention might assume.

herein shown and described.

l claim:

1. In a device of the class described, the' combination of a mainexhaust conduit,

spaced inlets -to said conduit said inlets being in the form of elbows,the opening with-l in the conduit presenting in the direction of flow ofgases through said conduit, and a flap valve hinged to said elbow andgravity actuated whereby the inward movement of the gases is notresisted but escape ofgases in a rearward direction is prevented, sub`stantially as described. 3. In adevice of thev class described, thecombination of an exhaust main provided .with spaced inlets thereto, aflexible tubular conduit removably connected to said main, said flexibletube teiiinating'in a conical coupli b means of which said'tube may beattac e to the exhaust pi e of an automobile, substantiall;- as descried.

I therefore do not wish tobe limited to the exact constructionl In adevice of thew'class described, the' f combination of a Waste gasconduit, a flexible tube removably connected thereto, said tube beingprovided with a conical cou cated in spaced relation in said conduit andproviding inlets forl`w aste gases, said velbows extending within theconduit and the -gases therethrough being directed toward the outlet insaidfconduit, and valves controlling said inlets, substantially as de#scribed.

7. In a device of the class described, the combination ofa common wastegas conduit having a plurality of inlets, one-way lvalves controllingsaid Vinletsfllexible tubes Aconnccted to said inlets, means forconnecting., the' free endsl of said tubes to an exhaust pipe, `and'automatic means for disengagir'ig the same therefrom, substantially as'de- 8.
